Tetra­Kis(Μ-2-Iodo­Benzoato-Κ2 O:O′)Bis­[Aqua­Copper(II)]

Abstract

In the centrosymmetric binuclear title complex, [Cu2(C7H4IO2)4(H2O)2], the two CuII ions [Cu⋯Cu = 2.6009 (5) Å] are bridged by four 2-iodo­benzoate (IB) ligands. The four nearest O atoms around each CuII ion form a distorted square-planar arrangement, the distorted square-pyramidal coordination being completed by the O atom of the water mol­ecule at a distance of 2.1525 (16) Å. The dihedral angle between the benzene ring and the carboxyl­ate group is 25.67 (13)° in one of the independent IB ligands and 6.44 (11)° in the other. The benzene rings of the two independent IB ligands are oriented at a dihedral angle of 86.61 (7)°. In the crystal, O—H⋯O inter­actions link the mol­ecules into a two-dimensional network. π–π contacts between the benzene rings [centroid–centroid distances = 3.810 (2) and 3.838 (2) Å] may further stabilize the structure.
